SPECIFICATION forming part of Letters Patent NO. 533,719, dated February5, 1895.

To all wit/077?, it may concern;

Be it known that we, CHARLES ALBERT MILLER and FREDERICK JOHN MILLER,subjects of the Queen of Great Britain, residing inthe city ofBirmingham, England, have invented certain new and useful Improvementsin Cycle-Lamps; and we do hereby declare the following to be a full,clear, and exactdescription of the invention, reference being had to theaccompanying drawings, which form part of this specification, and forwhich invention Letters Patent of GreatBritain have been granted to us,bearing date July 22, 1892, No. 13,391.

This invention relates to improvements in the construction oftwo-part-sectional lamps, and our said invention consists in jointingthe said sectional parts together in such manner, that the body part, orthe main body part, moves away from another and fixed partwhen a lamp isopened. By thus bodily turning away the said first named part, from thatof the said second named part, the interior parts of a lamp are exposedand more readily got at for cleaning and other purposes, than hasheretofore been accomplished.

Figure l of the accompanying drawings represents in side elevation,partly in section, a two-part jointed sectional lamp constructed,arranged and provided with improvements made according to our invention.The said figure represents the lamp closed, or the component sectionalparts in the positions which they assume when the lamp is in use. Fig. 2represents in section, with parts in elevation, the lamp open, or themovable and shell body part turned forwardly from the fixed back andupwardly from the base, which latter component parts remain quiescent,and have connected to them, the bracket or other arms employed inmounting the lamp. Fig. 3 represents the sectional component partsseparated, showing the joints at the upper ends or parts of both ofthem. Fig. 4 is aplan of the shell body part of the lamp separately.Fig. 5 representsa front elevation of the lamp when the same is fullyopened, or with the jointed and shell body part turn ed back so as tocome practically into the same plane as the fired back upon which it ishung, thus mak ing accessible and exposing the whole of the interiorsurfaces and parts of the lamp.

In Figs. 1 to 5, a is the shell body part, hav' ing an open'oruninclosed bottom a and also an open or uninclosed back a a is theclosed or solid front, carrying a glazed bell 0. with light aperture a,through it. a, are inclosed sides. The upper part of the said shell bodypart a, has a crown a ahood a and a breaker a and with the upper part ofthe said open back, at its junction with breaker, hood and crown,jointed or hinged at b, to the top or extremity of an upright and rigidback 0, directed from or carried upon the top side rear part of an oiltank 01, which forms the base or bottom to the lamp when the opened oruninclosed bottom and back body part is closed.

Jointedly connected to the middle of the outer side of the fixed back ofthe lamp, are bracket arms 6, having or carrying at their extremities, asocket plate and socket. (Not shown.) The said mounting is connected tothe back of the lamp by a hollow ventilated backstrap g, or other means.The lower extremities of the sides a at the open bottom a fit uponrabbeted edges d of the slightly raised top oi? the oil tank; hence themaking of the joints practically lightand weathertight when the saidbody or dislocated body part is closed, and also making the whole of theparts rigid. The fixed back carries an attachable and detachabledeflector h, so that when the dislocated body part of the lamp is swungupon its hinge joint, and the whole of the interior of the lamp of boththe fixed or movable parts exposed, the attachable interior parts can beremoved, or the whole cleaned, and the wick lighted or trimmed. One ofthe sides a, of the lamp body part is gapped at 0, for the clearance ofthe wick winder a, and which clearance 12., is covered over when thelamp is closed, by a closure plate a.

Fitted to the under side of the front of the lamp is an outstandingplate 11, carrying an inwardly disposed inclined lip, stay dowel orprojection '5 which is adapted to take a bearing upon the shoulder orinclined top part d of the mouth entrance d of a hole or recess themovable part of the lamp to take and (1 wherein the tongue spring catchj, works, and is adapted to engage with or snap behind the plate 1', asaforesaid. The fully closing of the movable and hinged body upon itsbase causes the slightly inclined lip or dowel i to impinge and bearupon the shoulder or top part d, of the mouth dfland by suchimpingement, the fixed back is prevented from being deflected or forcedout of the perpendicular by the force applied in fastening the movablepart of the lamp to the fixed part. Thus, by causing a projection ordowel part carried by bear upon the fixed part of the base, the saidmovable part of the lamp is stayed or tied in manner so as to preserve aconstant or fixed distance between the joint and its base. Thus it isobvious that unless such means of diagonal tying, as it were, the lampmovable part to the base during the fastening, were employed, theupright back would be immediately forced out of the perpendicular, inconsequence of the members forming as it were levers forcing againsteach other, by the hinged point of support of the upright back being soconsiderably removed from the base. In the base part, j is a tonguestop, for limiting the movement of the said free tongue catch j. It willbe seen that the opposite edges are provided with inwardly directedflanges, which when the lamp is closed, fit over the rabbeted back edgesa, of the open back Q of the body a, hence the making of the same bothweather and light tight and rigid.

We wish it to be understood that instead of the tank being employed asthe base to the lamp, we may employ a base or bottom with slightlyturned-up edges, and inclosed within the sides or resting upon the baseor bottom, a loose oil tank may be fitted, either to slide therein, orbe 0th erwiseattac-hably connected.

Having fully described our invention, what we desire to claim and secureby Letters Patent isl. A cycle lamp composed of a body part and albasepart, the body part consisting of two sections one having complete sidesand open back and bottom and the other section consisting of an uprightor plate mounted upon and carried by the base, the two sectionscomposing the body being hinged together at their upper portions and thesection having complete sides and open back or bottom being arranged andadapted to swing outwardly and upwardly so as to give access to thelamp, substantially as described.

2. In a cycle lamp the combination of the sectional body part composedof two sections hinged together, with a base part and mechanism forconnecting one of said sections to the base part and relieving the othersection of undue strain, substantially as described.

In testimony that we claim the foregoing we have hereunto set our hands.
